IWIPRQVEFWENT IN THE MANUFACTURE OF BRUSHES.

Specification forming part of Letters Patent No. QQQ, dated April 21, 1874; application led February 727, 1873.

To all whom it may concern Beit known that I, EDWIN CLINTON, of the city and county of Philadelphia, Pennsylvania, have invented an Improvement in the Manufacture of Brushes, ot' which the following is a specification:

rlhe object oi' my invention is to produce a brush with bristles ar 1anged in such a uniform mass as to render it especially applicable for varnishing purposes 5 and this object I attain by the prelimii'iary sorting ofthe bristles in the casing A, (illustrated iu Figures l and 2 oi' the accompanying drawing,) and by confining the same to a ferrule,'B, compressed to such a shape in respect to the handle D, which passes through the mass of bristles, that the desired result may be attained. (See Figs. 3, 4, and 5.) The case for sorting the bristles consists ci' thin metal or other suitable material, and is separated into two compartments by a partition, b, as shown in the vertical section, Fig. 1, the opposite sides c a of the case being curved inward toward the partition, as represented, and the ends being slightly curved at the bottom, as shown in the longitudinal section, Fig. 2.

Bristles of a superior quality nre placed, with their tine ends downward, in the two compartments of the case, and, as every bristle is more or less bent, it is arranged with its rounded side opposite the concave side ci the case-an arrangement by which increased elasticity is imparted to the brush. lire curved sides of the case cause the mass oi' bristles to assume, at the point of the brush, the desired taper. (Represented in Fig. 3.) The two cempartments of the case having' been thus filled with bristles, they are withdrawn in a mass, and without changing their relative position, and this mass is passed through the circular ferrule IV; Fig. 6, after which the thin end of the tapering handle M is inserted in the direction of the arrows, as shown by dotted lines in Fig. 5, into the mass of bristles, and the ymass oi' bristles being thus secured in the ferrule.

The sectional shape of that portion of the handle which is embedded in the mass of bristles is illustrated in Fig. 4, and this shape plays an important part in the nal distribution of the bristles into a compact mass of the desired shape, for opposite sides of the lower edge of the i'errule are compressed, as shown in FiO. 3, so that 'the ferrule at the said lower edge assumes the form illustrated in Fig. 4, which is in accordance with the sectional form of the thick portion of the handle, the bristles being confined between the two in such a manner that those which project beyond the ferrule assume a compact mass of the i'lat tapering form represented in the drawinga form which renders the brush especially appropriate for varnishing purposes.

I claim as my invention- 1. The inode, substantially as herein described, of manufacturing brushes-that is, depositing the bristles in separate receptacles, by which each bristle is caused to assume a position with its end curved toward the cen ter oi" the mass, withdrawing them While thus arran ged and securing them to the handle, as rpecilied.

' 2. A brush in which the bristles on opposite sides are arranged as described, so as to bend toward the center, as set forth.

A brush in which the upper ends of the bristles are conlined between the lower end of the handle and a t'errule having a mouth coinciding in shape with the handle, as specified.

iu testimony whereof I. have signed my name to this specitieation in the presence 0f two subscribing witnesses.
